Diverticulitis

How is the disease diagnosed?

Diverticulitis is suspected after a history and physical examination. A history of lower, left-sided abdominal pain is a clue. The physical exam often reveals a tender abdomen. Tightness of the abdominal muscles, called abdominal rigidity, suggests serious infection. The white blood cell count is often elevated. A test called a CT scan may be used to confirm the diagnosis.
